Yields Surge, $1.2B Foreign Cash Floods Indonesian Bonds — Biggest Monthly Inflow In Over A Year

Indonesia’s government bond market is poised to log its strongest monthly foreign inflow since May 2025, as aggressive monetary tightening pushes local yields higher and lures overseas capital back to prop up the rupiah.

Treasury data shows foreign investors recorded net purchases of $1.2 billion in state debt up to June 26, putting the market on track for a 12-month peak monthly inflow.

“Rising yields on Indonesian sovereign bonds have recaptured global investor attention,” Eugene Leow, Senior Rates Strategist at DBS Bank Singapore, commented. “On top of that, Bank Indonesia’s consistent rate hikes to stabilise the rupiah against a rampant US dollar have further boosted the appeal of rupiah fixed income assets.”

The capital turnaround stems from a front-loaded tightening cycle by Bank Indonesia. After a 50bp off-cycle hike in May, the central bank delivered another surprise 25bp increase on June 9, lifting the benchmark BI Rate to 5.50%Bank Indonesia. The move directly lifted benchmark 10-year bond yields from 7.1% to 7.3%, widening the yield premium over major developed market debt.

Official data confirms foreign demand rebounded immediately post-hike. Within two days of the June rate decision, over $1.06 billion poured into SRBI central bank securities and government bonds, with foreign buyers focusing heavily on short and medium-duration tenors. To amplify inflows, BI also rolled out supportive tweaks including lower FX hedging expenses and twice-weekly SRBI auctions to sustain elevated local yields.

The strong bond inflow marks a sharp reversal from Q1’s persistent portfolio outflows. Cumulative foreign fixed-income inflows for Q2 have hit $3.37 billion, though equities still face steady overseas selling pressure. Analysts flag that robust carry returns remain the core draw, even as geopolitical risks from the Middle East keep broad USD support intact.

Market watchers view the capital shift as solid evidence that Jakarta’s policy mix — higher yields paired with currency defence measures — has restored confidence in Indonesian assets, laying the groundwork for a broader recovery across local financial markets.
